Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
Fig. 1 is the structured flowchart of the source of early warning 10 for stirring host provided by the invention, as shown in Figure 1, this equipment comprises receiving trap 101 and control device 102, receiving trap 101 is for receiving the present current value of the motor of stirring host, control device 102 is connected with receiving trap 101, for performing following at least one: in concrete production process, the band calculating the current value under the present current value and normal production scenarios received carries current differential, this band is carried current differential to carry difference threshold with the band that presets and compare, and determine whether stirring host occurs seize according to comparative result, the output alarm signal when determining to occur seize, when stirring host zero load, calculate the no-load current difference of present current value and the no-load current value under normal circumstances received, this no-load current difference and the unloaded difference threshold preset are compared, and determine that seize appears in stirring host according to comparative result, output alarm signal.
It should be noted that, the normal production scenarios that the present invention mentions and normal condition refer to the situation that seize does not appear in stirring host.
Specifically, the electric current of the motor of stirring host is determined by the power of stirring motor and voltage, and when the voltage stabilization of the motor of stirring host, electric current is directly determined by power.And the resistance that the power of the motor of stirring host is produced by the axle of stirring host when stirring determines, so the resistance of the axle of stirring host is larger when stirring, then the electric current of motor is larger.And for the concrete of same label, in concrete production process, the resistance that the axle of stirring host is subject to after various raw material stirs is constant, so the electric current of motor is exactly constant, that is steady current is constant.In order to make result more accurate, the current value received in concrete production process that the present invention mentions is stable electrical flow valuve.Such as, so control device 102, before starting to perform and determining whether stirring host occurs the step of seize, first can judge whether electric current is stablized, can judge that whether the change of current value at 500ms be more than 0.5A.Here, judge that the whether stable process of electric current is the known technology of those skilled in the art, in this, it will not go into details.
Because the concrete steady current in process of production of different labels is different, so need to set different standards to the concrete of different labels.In one embodiment, receiving trap 101 can receive the concrete label of the current stirring of stirring host, and then the current value corresponding with this label under normal production scenarios determined by control device 102 according to this label.In another embodiment, receiving trap 101 can receive the proportioning of the raw material dropping into stirring host, then the concrete label of the current stirring of stirring host determined by control device 102 according to proportioning, then determines the current value corresponding with this label under normal production scenarios according to this label.
In order to information more accurately can be provided to operating personnel, above-mentioned band carry difference threshold can comprise the first band carry difference threshold and second band carry a difference threshold.In concrete production process, when the band received carry current differential be greater than the first band carry difference threshold and be less than or equal to the second band carry difference threshold, can determine that slight seize appears in stirring host, and export corresponding alerting signal; When the band received carry current differential be greater than the second band carry difference threshold, can determine that severe seize appears in stirring host, and export corresponding alerting signal.
Certainly, above-mentioned band carries difference threshold also only can comprise a band year difference threshold, such as, can be that the first band carries difference threshold or the second band carries a difference threshold, or other suitable values.In concrete production process, when the band received carry current differential be greater than this band carry difference threshold, can determine that seize appears in stirring host, and export corresponding alerting signal.
Correspondingly, above-mentioned unloaded difference threshold also can comprise the first unloaded difference threshold and the second unloaded difference threshold, when stirring host zero load, when the no-load current difference received is greater than the first unloaded difference threshold and is less than or equal to the second unloaded difference threshold, can determine that slight seize appears in stirring host, and export corresponding alerting signal; When the no-load current difference received is greater than the second unloaded difference threshold, can determines that severe seize appears in stirring host, and export corresponding alerting signal.
Certainly, above-mentioned unloaded difference threshold also only can comprise a unloaded difference threshold, such as, can be the first unloaded difference threshold or the second unloaded difference threshold, or other suitable values.When stirring host zero load, when the no-load current difference received is greater than this unloaded difference threshold, can determines that seize appears in stirring host, and export corresponding alerting signal.
It will be appreciated by those skilled in the art that the light and heavy degree of the seize of stirring host not only can be divided into " slight seize " and " severe seize " two ranks, multiple rank can be set as required, to reach more accurate early warning object.
It will be appreciated by those skilled in the art that control device 102 can be set as that recording a band at set intervals carries current differential in database, operating personnel can the change according to the observation with carrying current differential judge whether to need to clear up stirring host.In like manner, control device 102 can also be set as recording a no-load current difference at set intervals in database, and operating personnel can the change of no-load current difference judge whether to need to clear up stirring host according to the observation.
Such as, Fig. 2 band shown under the normal production scenarios that the concrete (concrete that the concrete mod sum label that namely label is C30 is C20) to two kinds of different labels records carries the curve map of current differential, wherein transverse axis is concrete agitator disk number, and the longitudinal axis is band year current differential.A part for current differential curve map is provide only in figure, in practical operation, operating personnel rule of thumb can set and occur that the band of seize phenomenon carries difference threshold, such as, band year current differential is observed not shown more than 2A(when operating personnel), can judge that slight seize appears in stirring host, when observing, band year current differential is not shown more than 4A(), can judge that severe seize appears in stirring host.It will be appreciated by those skilled in the art that the concrete for different labels, band carries difference threshold can be identical, also can be different.
Fig. 3 is the structured flowchart of the early warning system for stirring host provided by the invention, and as shown in Figure 3, this system not only comprises the source of early warning 10 for stirring host, also comprises pick-up unit 20 and warning device 30.
